It is located behind the medicine injection tube. The upper end of the medicine injection tube is screwed with a medicine storage bottle. The nipple of the injection cylinder is connected with a sheath through the diversion hose. The leakage hole communicated inside the sleeve, and the nipple of the syringe is provided with a one-way valve whose opening faces the sheath.

Compared with the prior art, the beneficial effect of the present utility model is: when administering intestinal medicine to a child, the sheath is inserted into the anus of the child, and the pendulum rod is repeatedly pushed to carry out a small amount of multiple injections, thereby reducing the amount of medicinal liquid. The stimulation to the inner wall of the intestinal tract reduces the situation of children expelling drugs due to intestinal stimulation when receiving intestinal administration, improves the work efficiency of medical staff, relieves the pain of children, and improves the treatment effect. The structure is simple and the operation is convenient. , The idea is novel and practical.

Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

1 to 4, including the front and rear axial injection barrel 1, the injection barrel 1 is coaxially provided with a pusher 2 that can slide back and forth, and the front side of the injection barrel 1 is provided with an up and down axial injection tube 3, The rear end surface of the pusher 2 is located behind the drug injection tube 3, the upper end of the drug injection tube 3 is threadedly connected with a drug storage bottle 4, the nipple of the syringe 1 is connected with a sheath 6 through a diversion hose 5, and the outer edge surface of the sheath 6 is provided with There are a plurality of leakage holes 7 evenly distributed along the circumferential direction and communicated with the inside of the sheath 6 , and a check valve 8 with an opening facing the sheath 6 is provided in the nipple of the syringe 1 .

In order to facilitate the front and rear movement of the pusher 2, the rear end of the pusher 2 is hinged with a push rod 9 in the front and rear axial directions, the lower side of the syringe 1 is provided with a handle 10 in the up and down direction, and the rear end of the push rod 9 extends out of the syringe 1. And it is hingedly connected with the handle 10 through the pendulum rod 11 .

In order to enable the swing rod 10 to automatically reset, a left and right axial torsion spring 12 is provided between the handle 10 and the swing rod 11 .

In order to prevent the medicinal liquid from flowing out when the medicine storage bottle 4 is installed, a fixing rod 13 is coaxially provided on the upper side wall of the medicine storage bottle 4, and a sealing plate 14 is coaxially slidably connected to the fixing rod 13, and the lower surface of the sealing plate 14 can be In contact with the lower side wall of the medicine storage bottle 4 , the fixing rod 13 is sleeved with a spring 15 located between the sealing plate 14 and the upper side wall of the medicine storage bottle 4 .

In order to make the liquid medicine in the medicine storage bottle 4 flow into the injection barrel 1 through the medicine injection tube 3, the upper end surface of the medicine injection tube 3 can be in contact with the lower surface of the sealing plate 14, and the upper side of the medicine injection tube 3 is provided with a plurality of edge The guide holes 16 are evenly distributed in the circumferential direction and communicate with the inside thereof. The upper side wall of the medicine storage bottle 4 is provided with a ventilation hole 17 which penetrates up and down, and a rubber plug 18 is detachably connected to the ventilation hole 17 .

In order to avoid damage to the intestinal wall of the child, the front end surface of the sheath 6 is a convex spherical surface.

When the utility model is in use, the medicine storage bottle 4 filled with the liquid medicine is rotated to connect the medicine storage bottle 4 with the medicine injection pipe 3. When the upper end surface of the medicine injection pipe 3 is in contact with the lower surface of the sealing plate 14, the medicine storage bottle 4 is rotated continuously. Bottle 4, the medicine injection tube 3 pushes the sealing plate 14 upward and squeezes the spring 15, the lower surface of the sealing plate 14 is out of contact with the lower side wall of the medicine storage bottle 4, and when the guide hole 16 is located inside the medicine storage bottle 4, the medicine storage bottle 4 The diversion hole 16 is communicated with the inside of the medicine injection pipe 3, and the medicine liquid in the medicine storage bottle 4 flows into the syringe 1 through the medicine injection pipe 3;

Insert the sheath 6 into the anus of the child, pull out the rubber plug 18 from the vent hole 17, hold the handle 10, push the swing rod 11 forward, and the swing rod 11 drives the pusher 2 to slide forward through the push rod 9, and simultaneously The torsion spring 12 is deformed, and as the pusher 2 moves forward, the pusher 2 gradually blocks the lower end of the injection tube 3, and the medicine in the storage bottle 4 cannot flow into the syringe 1, and the medicine in the syringe 1 is pushing. Under the action of the head 2, the one-way valve 8 is opened and flows into the sheath 6 through the diversion hose 5, and the medicinal liquid in the sheath 6 flows out through the leakage hole 7 and enters the intestinal tract of the child;
